Cisco Unified Call Manager 8.6.2 with CTS 1.8 720p Lite
When a CTS 1.8 endpoint that is configured to 720p Lite is registered to Cisco Unified CM 8.6.2, calls in secure mode sometimes drop. To work around this issue, either configure the CTS 1.8 720p Lite endpoint to non-secure mode or register the endpoint to Cisco Unified CM 8.6.1.

Important Notes
Adding or Removing a Presentation Codec
When you add or remove a CTS presentation codec in the system configuration, you must do so from the Cisco Unified CM Administration interface. After the configuration change is complete, click Reset to sync this configuration change with the CTS codec. See the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.
ASR and GSR Support
Only Aggregation Service Router (ASR) 3.2 is supported with CTS Release 1.8.0. The Gigabit Switch Router (GSR) is not supported.
Audio Echo Cancellation (AEC) on the CTS 500-32 and CTS 500-37
The Enable Audio Echo Cancellation (AEC) checkbox in the Cisco Unified Communications Manager Administration is not available for CTS 500-32 and CTS 500-37 systems running Unified CM version 8.5 and higher. To enable or disable AEC on these systems, use the set audio aec disable and set audio aec enable command-line interface (CLI) commands, as shown in this example:
1. Enable or disable AEC:
admin:set audio aec disable
AEC support state changed to disabled
2. Restart calling services to have this take effect:
admin:utils service restart Calling_Services
Calling_Services Restarting...doneadmin:
3. Verify the configuration:
admin:show config all
Enable AEC : Disabled
See the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System for more information.
Broadband Service Support
Customers can deploy Cisco TelePresence endpoints over Premium Broadband (Internet) such as business-class cable, FIOS, or E1 over the top. This gives customers flexibility to operate Cisco TelePresence across a variety of new connections.
All CTS endpoints and infrastructure must be upgraded to a minimum of Cisco TelePresence release 1.7 when broadband systems are deployed. Cisco TelePresence release 1.7 provides additional features to address the higher jitter and possible packet loss commonly found on broadband networks. Mixing CTS 1.7 systems with previous versions will disable the required CTS broadband network features, negatively affecting meeting quality, especially in multipoint meetings.
Calendaring on the Cisco TelePresence Touch 12
If the administrator leaves the roomName field blank in Cisco Unified Communications Manager Administration, the device calendaring features will not be managed by CTS-Manager. The Meetings button is not available on the touch device when the roomName field is blank.
3Release Notes for Cisco TelePresence System Software Release 1.8
When downloading MIDlet .jad and .jar files, use caution to avoid typos. Some files use a hyphen in the file string (“ - ”) and some use a period (“ . ”).
For example:
• TSPM-1.8.2-P1-1S.jar
• TSPM-1.8.2-P1-1S.jad
Note You must be running a minimum of Cisco Unified CM Release 7.0.2 to use MIDlets.
Cisco TelePresence T Series Endpoint Security
The Cisco TelePresence T Series endpoints do not register natively as secure endpoints; only non-secure mode is supported when talking to Unified CM.
Digital Media Player (DMP) Advisory
The DMP is always functional no matter the configuration on the Administration Web interface. The DMP Audio Administration configuration is set to indicate whether the audio will behave as a digital media player or as a PC; it does not turn the DMP capabilities on or off.
If the configuration is set to PC, the audio (whether coming from a DMP or a laptop) may be streamed to remote endpoints during a call. If the configuration is set to DMP, the audio (whether coming from a DMP or a laptop) may not be streamed to remote endpoints during a call.
The DMP button may not be visible after hours. See CSCtu19709.
Directory Settings in Unified CM
MIDlet does not support non UTF-8 characters so ensure that you use valid characters when updating the Directory feature in the Cisco Unified Communications Manager Administration interface.
End-of-Sale and End-of-Life Products
Customers with active service contracts will continue to receive support from the Cisco Technical Assistance Center (TAC) for the following products
• Cisco announces the end-of-sale and end-of life dates for the Cisco TelePresence System 1000:
Headsets are supported on the CTS 500 Series only.
Idle Display Field in Unified CM
Idle Display is a mandatory field in the Cisco Unified Communications Manager Administration interface. Specify any of the following options in the Idle Display field:
• Default Detailed
4Release Notes for Cisco TelePresence System Software Release 1.8
Security in a point-to-point call is supported between a CTS 1.8 endpoint and each of the following:
• Cisco TelePresence TC endpoint—Secure or non-secure, depending on the configuration of the Cisco TC endpoint.
• Cisco Unified IP Phones—Secure.
• Any of the Cisco interop endpoints listed in the matrix below—Non-secure.
For information on Cisco interop endpoints, see the Interoperability Between CTS Endpoints and Other Cisco Endpoints or Devices on Cisco.com.
Participant List Check Boxes
The check boxes next to active meeting participants on the Cisco TelePresence Touch 12 are view only; you cannot check or uncheck the entries.
Phone Screen Capture via Cisco Unified CM
Because the CTS codec is no longer the authentication server for the phone and cannot be used to obtain screenshots of the phone for diagnostics, you will need to create an End User profile to manage the phones and capture a screenshot. See the “Obtaining a Screenshot From the MIDlets Phone” section of the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.
Registering VLAN
If you want the CTS to autoconfigure itself with a VLAN without network interaction, set the Administrative VLAN in the Cisco TelePresence System Administration interface. To view or configure the administrative VLAN ID in the administration GUI, choose Configuration > Network Settings. See the Cisco TelePresence System Administration Guide for more information.
Resetting the CTS Factory Image
When you change the CTS model while performing configuration tasks in the administration interface (switching from a CTS 1000 to a CTS 1300-65, for instance), the CTS automatically reboots.
Resetting the Cisco Unified IP Phone 7975 Factory Image
Occasionally, an unexpected phone power cycle can occur during a CTS endpoint upgrade. During CTS endpoint upgrades, the CTS briefly powers off the phone then brings it back up when upgrade is complete. But if the phone power cycle is occurring at the same time, the phone's firmware image can be damaged and the phone will not power back on. This can also occur when upgrading the phone MIDlet.
To avoid this problem, schedule CTS endpoint or MIDlet upgrades when the phone is not in power cycle mode. If you encounter a phone that will not power back on after a CTS endpoint or MIDlet upgrade, perform a phone factory reset to restore the firmware image. For more information, see the Resetting the Cisco Unified IP Phone 7970 Series Factory Image section of the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.
5Release Notes for Cisco TelePresence System Software Release 1.8
For all SCCP and SIP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(3) or a later release, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your Cisco Unified IP Phone to version 8.5(3) or a later release.
See the Installation Notes section of the Cisco Unified IP Phone Release Notes for Firmware Release 8.5(3) (SCCP and SIP) for download instructions.
Setting the Device Type
By default the primary codec defaults to CTS 1000. To perform camera calibration on a CTS 3010/3020 if your system is not registered to the Unified CM, use the set ctstype <3000 3010 ...)> command. Whenever possible register your device to the Unified CM to configure the correct device type before calibrating the camera.
Single Microphone Mute
Single microphone mute is available with software upgrades beginning with Cisco Unified CM firmware release 8.0.3. This feature is configured using a disable/enable check box in the Cisco Unified CM Administration interface.
See the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.
SIP Max Incoming Message Size
You must set the SIP Max Incoming Message Size in Unified CM SIP to be greater than 5K. Otherwise it can cause issues with multiple hold/resume in interop calls with VCS and security. Cisco recommends setting it to 11000.
Updated Presentation Capability and Notification
If the remote endpoint does not support a 1024x768 presentation stream, the Not Sharing Presentation icon (a laptop with a slash through it) is displayed on the main screen along with the following message:
“Remote participant cannot receive presentation.”
While the CTS negotiates a lower frame rate, the following message appears:
“Please wait to receive video. Still sending video.”
Video resumes once the frame rate is negotiated. If the video takes longer to negotiate, the following message appears:
“Unable to receive video. Still sending video.”
Upgrading from a Cisco Unified IP Phone to a Cisco TelePresence Touch 12
For instructions on upgrading from a Cisco Unified IP Phone to a Cisco TelePresence Touch 12, see the “Upgrading From a Cisco Unified IP Phone to a Cisco TelePresence Touch 12” chapter of the Cisco TelePresence Touch 12 User Guide.
Upgrading from CTS Release 1.7 to CTS Release 1.8
Note If you are upgrading from any CTS release prior to 1.8.0 and using the Touch 12 device, refer to the “Understanding COP and Loads Files for the Cisco TelePresence System” chapter of the Cisco TelePresence Touch 12 Installation Guide.
6Release Notes for Cisco TelePresence System Software Release 1.8
When upgrading from any CTS 1.7 release to CTS Release 1.8.0, the system automatically upgrades slot 0 to CTS 1.8.0 if the existing CTS release in slot 0 is lower than CTS 1.8.0. Some systems upgrade more quickly than others:
• Cisco 3x00 Series, Cisco 1100, and Cisco 1300—Upgrade completes in approximately 1 minute and 30 seconds.
• Cisco 500-32 and Cisco 1300-47—Upgrade completes in approximately 4 minutes and 30 seconds.
Viewing Presentations on Laptops
The VGA cable interface requires a 60 hertz refresh rate, but some laptops receive 60hz but do not send 60hz. For best results when viewing presentation displays on your laptop, try the following:
• Perform an Fn+F7 to disable the presentation first and then use Fn+F7 to enable the presentation again (not necessary on Mac systems).
• Set the refresh rate in the monitor settings to something other than 60hz, then set it back to 60hz.
• Make sure that you have set your laptop resolution to 1024 x 768.
Web Access
To avoid having to start the Cisco TelePresence application manually after uploading the new image or restarting the CTS, make sure that web access has been enabled in the Cisco Unified Communications Manager Administration interface. See the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System for more information.
Web Browser Support
Cisco administration interfaces are supported on Internet Explorer (IE) version 6 (recommended).
WebEx Presentation
If the Cisco TelePresence room already has a presentation cable plugged in once the Cisco WebEx client stops presenting, the display in the room switches to the Cisco WebEx welcome screen rather than to automatic presentation. Cisco TelePresence room presentation is automatically active only if the Cisco TelePresence room plugs in the presentation cable again after a remote participant has presented.
WebEx Presentations with Cisco TelePresence Touch 12
When a Cisco TelePresence room is in a Cisco WebEx meeting, once the Cisco WebEx client has stopped sharing a presentation, the Cisco TelePresence room must plug the presentation cable in or unplug it then plug it back in again for the Cisco TelePresence room to take over the presentation role.

BFCP over UDP Collaboration Support
Binary Floor Control Protocol (BFCP) is used for controlling access to the media resources in a meeting. BFCP allows the CTS and the remote endpoint to view presentation and main display video simultaneously with improved presentation resolution for all third-party telepresence endpoints.
9Release Notes for Cisco TelePresence System Software Release 1.8
The CTS offers three media lines: one for audio, one for the main video, and the other for presentation or content using the session description protocol (SDP). Additionally, an application line is sent in the SDP for the BFCP control channel. The bandwidth of the presentation media line matches the capability of the CTS. For example, if the CTS is capable of 30 fps, the presentation media line bandwidth will be 4Mbps.
Note The CTS uses BFCP over user datagram protocol (UDP) in both secure and non-secure BFCP modes. BFCP is supported in CTS Release 1.8 and supports only Unified CM release 8.6.1.
To enable BFCP, the trunk from the Cisco Video Communication Server (VCS) to Unified CM must have a custom BFCP profile configured in the Cisco Unified Communications Manager Administration interface. This profile needs to be associated with every trunk and device that will use BFCP for presentation.
To configure BFCP for presentation, you must do the following:
1. Configure the Cisco VCS Zone for Unified CM.
2. Create a BFCP SIP profile in Unified CM and check the “Allow Presentation Sharing using BFCP” box.
3. Choose your new BFCP SIP Profile from the SIP Profile drop-down menu in the Protocol Specific Information field in Unified CM.
4. Restart all CTS endpoints.
5. Select the VCS trunk in Unified CM and set it to use BFCP.
See the following support documentation on Cisco.com:

11Release Notes for Cisco TelePresence System Software Release 1.8
The Cisco Options Package (COP) file is a mechanism for installing files on a Unified CM in a secure manner. COP files are zipped .tar files that the Unified CM verifies, unzips, and untars so that the contents can be installed in the Unified CM from either a local or a remote source. Unified CM automatically extracts the codec and device files from the COP file and applies them to your Cisco TelePresence system.
Tip Systems that are running Cisco TelePresence System software release 1.7.4 or 1.7.5 can use a COP file to upgrade and install their software with limited feature support. Full feature support is available in CTS Release 1.8.0. CTS Release 1.7.4, 1.7.5, and 1.8 continue to support .sbn and jar/jad files.
Find the COP file in the “Download” section of the Cisco support site for your product, located at the following URL:
http://www.cisco.com/cisco/web/support/index.html
For more information about installing COP files in Unified CM, see the following documentation on Cisco.com:

Administrators can provision their systems with DHCP option 60 when providing converged services in their network environment. DHCP option 60 is enabled on a customer’s DHCP server by the customer’s administrator.
12Release Notes for Cisco TelePresence System Software Release 1.8
To allow more Cisco WebEx users to access meetings remotely, you can configure up to five Cisco WebEx servers with your CTS-Manager account. The meeting organizer can register the CTS-Manager with any one of the five configured Cisco WebEx servers.
See the Cisco TelePresence System Manager home page for support documentation.
Security Enhancements
CTS Release 1.8 introduces the following security enhancements:
• Diffie-Hellman, page 13
• Secure Icon Behavior, page 13
• Session Parameters, page 13
Diffie-Hellman
To provide an additional level of security, Datagram Transport Layer Security (DTLS) clients will offer RSA as well as the Diffie-Hellman (D-H) key exchange mechanism. If the remote endpoint supports D-H, then the handshake is performed using D-H. The DTLS handshake with endpoints running releases prior to CTS Release 1.7.4 and 1.8 perform the handshake using RSA. This modification enables two CTS 1.7.4 or CTS 1.8 endpoints communicating with Unified CM releases prior to 8.5 to perform the DTLS handshake using D-H. The CTS uses the signaling path to exchange the fingerprints of the certificate used in the DTLS handshake. The certificate received in the DTLS handshake will be validated using the fingerprints.
Secure Icon Behavior
In certain calls involving a conference bridge, Unified CM downgrades a call status to non-secure. This could happen when a non-secure endpoint joins a conference, which has been secure. Unified CM sends SIP updates to the CTS indicating that the call is non-secure. CTS shows the secure or non-secure icon (closed or open padlock image) if the media is set up to use either of the following:
• SDP keys due to DTLS failure
• DTLS keys have been exchanged using fingerprint
Note The SIP updates are be ignored if the call is using DTLS keys but the DTLS handshake is setup without fingerprints.
Session Parameters
Secure Real-time Transport Protocol (SRTP) security defines a set of “session” parameters, which optionally can be used to override SRTP session defaults for the SRTP and Real-Time Transport Control Protocol (SRTCP) streams. These parameters configure an Real-time Transport Protocol (RTP) session for SRTP services. The session parameter provides information required to establish the SRTP cryptographic context for the session. The CTS negotiates the SRTP session parameter and honors the negotiated parameters.
Unified CM/Cisco VCS Security Support
CTS Release 1.8 introduces support for secure calls with the Cisco TelePresence EX and Cisco TelePresence C Series endpoints through Unified CM/Cisco VCS deployment.
The network is set up as follows: CTS > Unified CM > Cisco VCS > Cisco TC
13Release Notes for Cisco TelePresence System Software Release 1.8
Broadcast customers who want to remove the Cisco logo from their video presentations when it interferes with on-screen elements can do so in the Unified CM Administration interface by downloading a broadcast license. Contact your account representative to obtain the license.

Caveats in the CTS 1.8 Releases
Addressing with CTS Deployments
Deploying CTS endpoints in a network with both 10.x.x.x addresses and 192.168.x.x addresses may result in routing errors.
CTS endpoints reside on two networks simultaneously; an “external” network by which it communicates with other CTS endpoints and the internet, and an “internal” network by which it communicates with internal devices such as cameras, UI devices, etc. When a CTS endpoint comes up, it tries to pick an internal network address that does not conflict with the external network's address space. By default, it uses several RFC 1918 Class C subnets (192.168.xx) to address internal devices. In the event that the External network is based out of a network with the 192.168 prefix, a RFC 1918 Class A subnet (10.0.xx) is used to address the internal devices. When a CTS endpoint sends a packet, it chooses the most specific route in its routing table. Thus, if there exist two devices with the same IP address, where one is on the internal network while the other is on the external network, all packets emanating from the CTS will be sent to the internal network rather than the external network.
In this case, when the CTS on the right tries to send a packet to the CTS on the left, it will instead be routed (internally, by the CTS) to the Peripheral that is directly attached.
BFCP Backward Compatibility
BFCP is not supported in CTS software releases prior to CTS Release 1.8. BFCP is enabled by default on all CTS endpoints beginning with CTS Release 1.8. Endpoints using CTS software prior to CTS Release 1.8 must either disable BFCP on all new SIP profiles in the Unified CM Administration interface or upgrade all CTS endpoints to CTS Release 1.8.
Black Bar During Presentation
Some telepresence systems do not accept presentations at the recommended 1024x576 resolution. Occasionally a black bar is displayed during a presentation.
Cisco TelePresence EX Series “Best Effort” Audio-Addin Support
Non secure audio-addin calls are dropped from the Cisco TelePresence EX Series automatically when Encryption is set to On in the Cisco TelePresence EX Series administration. Go to Configuration > Conference > Default Call > Encryption and select “Best Effort” from the drop-down menu then click Save to allow audio-addin calls to continue. Secure call settings are still supported on the CTS endpoint but you must configure the Cisco TelePresence EX Series for Best Effort if your conference will include audio-addin calls, which are non secure by default.
Cisco TelePresence Touch 12 Troubleshooting
Sometimes the Incoming Call window overlaps the incoming call override button during troubleshooting or the Incoming Call window does not automatically disappear. This is a cosmetic issue. Tap the available Answer, Ignore, or iDivert buttons or simply allow the call to ring until it ends automatically. Configure iDivert in the Cisco Unified Communications Manager Administration.
Command-line Interface (CLI) Restrictions
Avoid using the following commands to collect call status logs while in an active call:
• file tail
• ipsla

Caveats in the CTS 1.8 Releases
Cisco Unified IP Phone 7985
Cisco announces the end-of-sale and end-of life dates for the Cisco Unified IP Phone 7985G.
There are known interoperability issues between the Cisco Unified IP Phone 7985 and the CTS 1300 Series; audio addin can cause the CTS main display to freeze.
Detect and Disconnect Audio Addin Calls
Occasionally an audio addin call remains listed on the meeting participant Conference List even though the call has dropped. Due to the call preservation feature, the CTS waits for the Unified CM to send a BYE message before dropping an audio addin call. The CTS can enact several mechanisms to detect when the audio addin has dropped, including dropping the call when the phone has been rebooted.
The CTS cannot support two audio addin calls at the same time.
Directory Entries for Cisco TelePresence Touch 12
When Directory entries are added or updated in the Cisco Unified Communications Manager Administration interface, an erroneous LASTNAME entry is listed on the Cisco TelePresence Touch 12. This is a cosmetic issue that does not affect functionality; there is no last name entry requirement in the administration interface for directory listings.
Document Camera Swap
Make sure that you reset your CTS any time that you swap document cameras that are running different firmware versions. See CSCtt93919.
Double-talk on the Cisco TelePresence System
During double-talk (when both sides are talking simultaneously), two things happen:
1. The audio from the remote side is slightly lowered before it is played out of the speaker.
2. Echo cancellation removes some of the sound from the talkers.
Endpoints That Cannot Share or Receive Presentations
Some telepresence endpoints do not support the ability to share or receive presentations. If you encounter an endpoint that does not support presentations, the CTS displays the following notification on the main screen:
“Remote participant cannot receive presentation”
Limited Bandwidth Mode: 360p
You may see the “Limited Bandwidth Mode: 360p” option in the Unified CM administration Quality (per Display) field. This choice will be available in a future release and is not available in CTS Release 1.8.
MXP Support on the Cisco TelePresence System
Observe the following notes about the Cisco TelePresence System MXP Series:
• The CTS sends 360p, receives 360p, and there is no presentation support.
• The CTS sends 360p, receives CIF, and bidirectional presentation is supported.
• The Cisco TelePresence System MXP 1000 SCCP does not support presentation.
17Release Notes for Cisco TelePresence System Software Release 1.8
A cosmetic issue occurs when there are more than five participants in the participant roster list on the Cisco Unified IP phone. Sometimes there are blank entries in the list as the user scrolls up and down to see the entire list. Feature functionality is not affected.
PiP Control
Some systems may show the Presentation-in-Picture (PiP) controls briefly while sharing presentations. Ordinarily PiP is not available during presentations. This is a cosmetic issue that occurs when the system tries to negotiate an unsupported DVI screen resolution.
Recording with Cisco TelePresence Touch 12
Sometimes the Cisco TelePresence Touch 12 active meeting screen flashes momentarily when the recording window is opened in preparation for recording the meeting. This is a cosmetic issue that corrects itself in a few seconds and does not affect functionality.
SDP and SRTP with CTS Release 1.7.4 and CTS Release 1.8.0
Customers who are deploying their B2B infrastructure with secure trunks to ASR/SBC secured by using TLS/Encryption, may experience call drops unless specific scripts are installed and configured on the ASR/SBC devices. Once the scripts and configuration are in place, certain SDP attributes are manipulated to enable SBC to unblock the SIP messages to and from Unified CM.
The following is an overview of the configuration steps:
1. Upload attached srtp.lua script to your ASR1k.
2. Define two SDP editors, for example to_rtp_avp and to_rtp_savp.
3. Configure a script set, as shown in the following example:
script-set 2 lua script srtp filename bootflash:srtp.lua load-order 100 type full complete active-script-set 2
4. Use the SDP editor on both the inbound and outbound adjacencies:
– Ask SBC to modify the SDP calling to_rtp_avp before-receive
The first two are used in the inbound side, which will detect if any X-cisco-srtp-fallback tag gets into the supported header and then adds an srtp-fb header that includes the X-cisco-srtp-fallback tag (if present). The third one changes the internal srtp-fb header to the supported header prior to sending on the wire. The following is an example configuration:

Sharing Presentations from the Cisco E20 IP Video Phone
The Cisco E20 IP Video Phone does not support BFCP for 1024x768 presentation and therefore the CTS cannot send presentations to the Cisco E20 (CSCtu75116).

A remote code execution vulnerability in the implementation of the Cisco Discovery Protocol (CDP) component could allow an unauthenticated, adjacent attacker to execute arbitrary code with elevated privileges. The vulnerability is due to a failure to properly handle malformed CDP packets. An attacker
23Release Notes for Cisco TelePresence System Software Release 1.8
OL-24611-01
Caveats in the CTS 1.8 Releases
could exploit this vulnerability by passing malformed CDP packets to an affected device. Successful exploitation of this vulnerability could allow the attacker to execute arbitrary code with elevated privileges.
Because CDP works at the data link layer (Layer 2), an attacker must have a way to submit an Ethernet frame directly to an affected device. This action may be possible in situations where the affected system is part of a bridged network or connected to a non partitioned device, such as a network hub.
This issue was disclosed in the following Cisco Security Advisories:
A remote command injection vulnerability exists in one of the Cisco TelePresence APIs that are hosted on the immersive endpoint devices. This issue, if exploited, could allow an unauthenticated attacker in an adjacent context to execute arbitrary commands on the underlying operating system with elevated privileges.
An attacker must have the ability to submit a malformed request to TCP port 61460 from a physical or logical Layer 3 adjacent context. A three-way handshake is required to exploit this vulnerability.
This issue was disclosed in the following Cisco Security Advisory:
When a Cisco TelePresence System 3000 Series system that is registered to Cisco Unified Communications Manager (Unified CM) is sending video using a document camera, some EX series systems that are registered with a Video Communication Server (VCS) receive scrambled video.

Supported CTS Auxiliary Devices
Cisco TelePresence Touch 12 Resolved Caveats in CTS Release 1.8.0
There are no known resolved caveats in this release.
Caveats in Prior CTS ReleasesSee the Cisco TelePresence Administration Software Release Notes home page on Cisco.com for information about prior CTS releases:
Supported CTS Auxiliary Devices This section contains auxiliary devices that can be used with the Cisco TelePresence System:
• Displays, page 45
• Document Cameras, page 45
• Projectors, page 46
• Video Signal Splitters, page 46
DisplaysCisco TelePresence systems are designed to work with any Full HD monitor that connects to the system using a standard HDMI or DVI interface. Note that the connector on the TelePresence side is an HDMI connector, so either an HDMI-to-HDMI cable or an HDMI-to-DVI cable is required.
Cisco highly recommends the use of commercial or professional-grade displays with your Immersive TelePresence system. Off-the-shelf consumer displays or TV monitors are not recommended, as they typically have shorter life spans and require a remote control to operate.
When qualifying a display for use with your TelePresence system, consider the following:
• The display should offer native support for 1080p60 over an HDMI or DVI interface.
• The display should become active when a video signal is presented, and should go to sleep when no video signal is presented.
• The display should not require any user interaction (such as a remote control or button press) to become active from standby, sleep or deep sleep modes.
• The ability to switch off On-Screen Display (OSD) messages is highly desirable. No error messages, status messages or splash screens should be visible on the screen when a presentation image is shared or unshared.
• If the display supports multiple inputs, the ability to lock the display to a given input is highly desirable. Otherwise, the time required to show presentation content can be unpredictable. If automatic scanning of ports is supported, the feature should be disabled.
Document CamerasThe following WolfVision document cameras have been tested for use with Cisco TelePresence Systems:
45Release Notes for Cisco TelePresence System Software Release 1.8
Note Cisco maintains support for the Sanyo PLV-Z4 and Sanyo PLV-Z5 projector models in older CTS configurations.
Video Signal SplittersThe following video signal splitters have been tested for use with the CTS:
• GEFEN EXT-HDMI-144
• EXT-HDMI-144-BLK
• GEFEN EXT-HDMI1.3-144
• GEFEN GTV-HDMI1.3-144
Note Using External Devices with Your Cisco TelePresence System—Cisco cannot guarantee the performance of any external device, so Cisco recommends that you choose good quality external devices to optimize CTS performance.
The CTS works best when suitable devices are attached using good quality cables and connectors. Cisco does not supply the cable that connects auxiliary devices to the codec.
Caution In European Union countries, use only devices that are fully compliant with the EMC Directive [2004/108/EC].
For information about managing video signal splitters, see the Routing Power and Signal Cables chapters of the following guides on Cisco.com:
• Cisco TelePresence System 3000 Assembly, Use & Care, and Field-Replaceable Unit Guide
• Cisco TelePresence System 3200 Assembly, Use & Care, and Field-Replaceable Unit Guide
